36 lbs./hr. High-Flow Fuel Injectors

The Top Street Performance Velocity High-Flow Fuel Injectors are engineered to provide precise fuel metering and consistent cylinder-to-cylinder delivery for GM LS1, LS2, LS6, and 5.0L Coyote applications. This set includes eight injectors, each with a flow rate of 36 lbs./hr. and a high impedance, making them suitable for various EFI upgrades. The injectors feature a USCAR plug style with a 12V saturated circuit driver type. Their physical dimensions include a seat-to-seat height of 2.078 inches, a maximum outside diameter of 0.580 inches, a manifold O-ring outer diameter of 0.580 inches, and a fuel rail O-ring outer diameter of 0.551 inches. Confirmation of fuel rail and intake manifold fitment, as well as injector depth, is recommended before installation. Installation of these injectors requires careful calibration to match the ECU, fuel pressure, and engine's fuel demand. Adapters may be necessary for certain applications, such as the conversion from EV1M to EV6F connectors for LS1 fitment, which are included. The manufacturer notes that larger or different injectors typically require ECU tuning for optimal performance and proper fueling. This product is intended for racing and off-road competition use only and is not legal for use on public roads or emissions-controlled vehicles. Common vehicle applications include Chevrolet Silverado, GMC Sierra, Chevrolet Camaro, and Chevrolet Tahoe. Compatibility is also confirmed with specific TSP Velocity intake manifold and fuel rail combinations, including part numbers 81001, 81002, and 84050.
